  • Patent number: 10697443
    Abstract: An exhaust air conduit for a pneumatically powered pump, in particular, from a coating agent pump in a painting plant, is provided. The conduit includes an inlet for receiving the exhaust air from the pump, an outlet for discharging the exhaust air, and an exhaust air channel in which the exhaust air flows from the inlet to the outlet of the exhaust air conduit, and a housing member in which the exhaust air channel extends. A first thermal insulation element is provided in the region of a direction change of the exhaust air channel, in order to prevent an accumulation of the exhaust air directly at the inner wall of the exhaust air channel and thereby to lessen the cooling of the housing member.

  • Patent number: 9192936
    Abstract: A method for crushing and drying damp wood, wherein the wood is introduced into an impact reactor, which has a substantially cylindrical main body, in the closed interior space of which there rotates a rotor with at least one impact element, which contacts the wood and crushes it into part-constituents while generating a great transfer of momentum. The interior space of the cylindrical main body is assigned a suction removal device, which during the impact crushing removes the mist of moisture produced when the impact element makes contact with the material, and the interior space of the cylindrical main body has admitted to it hot gas, heated by waste heat from a combustion process, at a temperature of less than 95° C., in particular less than 80° C., or the exhaust gas from a combustion process, which after a collision of the impact element with a material constituent penetrates the material constituent in place of the moisture leaving. Also a device for carrying out the method.
